Are Zzp coil packs good?

These high voltage coil packs will supply a stronger spark which will allow you to run a larger gap that will improve fuel economy, driveability, and HP capability. Not an earth shattering difference but a small gain. Definitely well worth the upgrade if you’re replacing your coils.

Do coil packs increase horsepower?

Although the new coil packs produced 40,000 volts under load, as opposed to 25,000 volts for the stock ones, it was always known that aftermarket ignition systems, high voltage coils, etc. did not result in horsepower gains for low rpm stock engines.

What happens when coil packs go bad?

Coil Pack Problems Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. This causes what’s commonly referred to as misfiring. Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.

What makes coil packs go bad?

Coils fail for a variety of reasons including heat, vibration, or issues on the secondary side of the ignition system. Worn secondary ignition components such as spark plugs or wires can cause a coil work harder, require more voltage, and therefore significantly reduce the operating life of the coil.

Where are Delphi coils made?

China
It is different then the original, even though it says Delphi on it, it is made in China and really looks like a generic coil with the name Dekphi added to it.

Do coil packs wear out?

Many coil packs don’t require service for up to 120,000 to 150,000 miles. Also, distributors are very prone to failure if they become wet or the engine happens to be submerged under water for a few seconds. Coil packs tend to operate even when they have been thoroughly doused with water.

Are some coil packs better than others?

In the world of performance, more is almost always better. More boost, more airflow, more fuel, more horsepower, more performance, etc. However, more voltage does not always mean better in the world of ignition coils. Davis says that the OEM coils were notorious for drop off above or about 5,000 rpm.
